running database on another computer

I've built an application that displays the contents of an access database in a datagrid and also a form which allows a user to add a new record to the database.
When I tried to run the exe in the bin folder on another computer it displays an error when I try to add a new record to the database.
It allows me to view the records in the datagrid no problem but will not run my query on a different computer. Any help would be greatly appreciated

It is not shared on a network. I was trying to take it from my home pc and run it on another pc in a different location. I copied the entire project folder to another computer and ran the exe in the bin/debug folder.

I believe so. I am not at home at present so cannot look. I did not code in the connection I used the OleDbConnection from the toolbox and connected it to my database from there. I am still novice with VB.net so I apologise if I am not answering your questions very well

Module Module1
Public connectionString As String = "Data Source=HP-PC;Initial Catalog=VBP;user ID =sa; password= 1234"
Public loggedUserId As String
Public loglevel As String
Public loggedpassword As String
End Module

there in datasoure you put the IP address of the computer you connected.
Initial Catalog:-databasename
